.357 Magnum vs 10mm – Why Does Everyone Pick The Wrong One?

The cartridge forums have been lying to you for a decade about the 10 millimeter versus the 357 Magnum. And the number one pick I am about to give you breaks the one rule every GT tuber swears is unbreakable. Two guns sit on my bench under the light right now. On the left, a Smith and Wesson 357 Magnum.

Blue 4-in barrel, six rounds of 125 grain hollow point sitting next to it, one on its side like it just rolled off the loading block. On the right, a stainless 1911 chambered in 10 mm. Full-size government frame. Four rounds of 180 grain fanned out beside it. One on its side, too. Same light, same bench.

Two answers to the exact same question. A buddy of mine is texting me right now. Works construction, saved up 800 bucks, asking which one he should buy for a woods gun and a nightstand gun and a truck gun all rolled into one. He has already been on the video sites for a week. He has already been told the answer by a channel that never fired either one of these with intent. He is not dumb.

A lot of good folks get talked into it, and that is exactly why I’m making this. I’m going to rank the 12 most common ways people actually buy into this fight. 12 specific guns and loads across both camps, worst to first, against one simple filter. My number one is going to start arguments in the comment section that will still be going next Christmas.

It breaks a rule everybody on the internet swears is unbreakable. The rule that says more rounds always wins. More energy always wins. More everything always wins. It is not what the loudmouth at your range told you. Once you see why it wins, you are going to feel a little dumb for how sure you used to be. I did.

Two guns, one right answer. Let me say one thing, then I’ll leave it be. Everything I’ve picked up behind that counter, how to buy right the first time, what’s worth your money and what ain’t, I put it all in one book over at reccalahan.com. If you want it, it’s there. That’s all. Now, let’s get back to it. Here is the filter, and it never changes for the next 30 minutes.

Does the gun still run when the stores are empty and your hands are cold? And is it worth what they are asking? Life or dollars? That is it. Not muzzle energy on a chart. Not capacity on a spec sheet. Not what some operator in sunglasses said on a podcast. Every gun and every load on this list gets measured against that same yard stick.

No favorites, no brand loyalty, no cartridge tribalism. I am Rhett Callahan. I run projects at a custom rifle and pistol shop outside Knoxville, which means damn near everything you are going to see today has crossed my bench in some form. apart, back together, or across the chronograph. I am not selling you a gun.

I am helping you buy the right one. Here is what the capacity is king crowd will not tell you straight. Most of them have never shot a full house 10 mm past 50 rounds in a session. And most of them have never carried a magnum revolver for real work a single day of their lives. They rank cartridges by muzzle energy the way teenagers rank cars by horsepower on paper with their thumbs. 12 picks, six from each camp.

Revolvers and semi-autos, budget and premium, hunting loads and defense loads, worst to first. Same treatment every time. Who built it? What the numbers actually say, what job it wins, where it breaks down, and what you ought to pay. The real question is not which cartridge is cooler. It is which one you will actually carry, actually train with, and actually feed when the shelf is empty.

Once you see it that way, you cannot unsee it. Number 12, the Rock Island Armory full-size 10mm 1911. The budget gateway drug into Cooper’s cartridge and where most 10 mm dreams go to die. Rock Island has been building 1911s in the Philippines since the 80s under Arms Corps. Cranking out working man pistols at prices Colt has not touched since Nixon was in office.

They chambered the full-size platform in 10 millimeter in the mid 2000s to ride the Cooper revival wave. The one that started when people finally admitted the Federal Bureau of Investigation made a mistake watering the cartridge down into 40 Smith and Wesson back in 1990. Armscore did not invent the 10mm 1911. They just made it cheap.

10 millimeter auto, 8 plus one, 5 inch barrel, 38 ounces empty, and pushing 44 loaded. Cast frame, forge slide, parkerized finish, full house, 180 grain, running around 1,250 to 1,300 ft per second out of that 5 in tube. That is real energy. Call it 625 to 675 foot-lb at the muzzle. On paper, it walks with a 41 Magnum.

On paper, for a range gun and a truck gun, it is an honest deal. Where it cost you against the filter, reliability out of the box is a coin flip. I have had two on the bench in the last year. One ran like a Rolex. The other would not feed Buffalo bore pass magazine 3 because the extractor tension was set for target loads.

Full House 10 mm needs a tuned gun. This one is not tuned. 500 bucks street, sometimes 450 on sale. cheap way in, but 10 mm ammo is a $150 a round on a good day. And the gun one step up gets you the same cartridge with a slide that actually likes hot loads. Number 11, the Taurus Tracker and .357 Magnum 4 in the budget revolver everyone talks themselves into then quietly trades.

Taurus has been building revolvers in Porto Allegre, Brazil since the 1940s. And the Trackr line dropped in the early 2000s as their answer to the mid-frame magnum market Smith and Ruger owned. Sevensh shot cylinder, one more than the Smith 686 in its early guns and a ported barrel.

Marketed as the working man’s magnum, the old Rossi and Amado Rossi guns share a lot of the same DNA under the finish. 38 special and 357 Magnum. Seven shot cylinder, 4-in ported barrel, 34 oz. Ripper grip that actually eats recoil better than most stock revolver stocks. 125 grain Magnum out of that tube runs around 1,400 ft per second.

Near textbook 357 Magnum numbers. On paper, it competes with any Smith or Ruger at half the price. For a range gun and a plinker, it works. Against the filter, the trigger, and the lock work quality control is where it cost you. I have seen three cross the bench with light strikes on the second or third round of the cylinder after the crane loosened up.

Taurus warranty is fine, but you are mailing the gun to Georgia for 6 weeks. That is not a gun you stake your life on. 400 bucks new, 300 used. Cheapest working magnum on the market, but cheap on a defensive revolver is a false economy. The wheel gun. One step up is where the story actually starts. Number 10, the Ruger GP 100 4 inch 357 Magnum.

The revolver that does not die, does not quit, and does not apologize. Bill Ruger’s team designed the GP100 in 1985 to replace the old security 6. And the mandate was simple. Build a mid-frame Magnum that could shoot full power. 357 Magnum loads all day, every day without shooting itself loose. It succeeded. It has been in continuous production ever since, unchanged in the ways that matter.

And it is the revolver every police armor of a certain age has strong feelings about. 38 and 357 Magnum, six shot cylinder, 4in full lug barrel, 40 ounces of stainless steel, triple locking cylinder, front, rear, and bottom, which is the reason it eats a diet of magnum ammo other guns choke on. And here is the 2020 story.

When the shells went bare that spring, 38 special and 357 were among the last handgun rounds still sitting on pegs at half the shops around me. Commonality matters. For a nightstand gun, a truck gun, a woods gun in Black Bear Country with the right load, it is the definition of enough. Where it cost you against the filter, the double-action trigger out of the box is heavy.

12 lbs is common on a new one. It smooths out around a thousand rounds of dry fire, but you have to put the work in. Most guys do not. They shoot it twice, decide revolvers are hard, and buy a Glock. 800 Street, 650 used for a clean one. Buy once, cry once. And the semi-auto competing with it costs the same and shoots twice. Number nine, the Glock 29, the subcompact 10 mm.

the concealment argument for Cooper’s cartridge, and it is not a bad one. Glock introduced the G29 in 1997, taking the fullsize G20 and chopping it down for concealed carry. A generation 4 came around 2012. It is the gun the 10mm faithful point to when someone says the cartridge is too big to carry.

It is Cooper’s ballistic idea in a package Cooper would have said was too small for the cartridge. 10 millimeter auto, 10 plus one in a flush magazine, 3 and 3/4 inch barrel, 27 O loaded. Full house 180 grain out of that short tube drops to about 1,200 ft per second, 575 ft-lb, still hotter than any 9 mm, still more than a 357 Sig.

You lose velocity to the short barrel, but you keep the diameter and the mass. For a bare country carry gun in Alaska or Montana back country, this is legitimately the smartest choice on the list. Against the filter though, recoil in a 27 ounce polymer subcompact with a full power load is genuinely unpleasant. Most owners feed it downloaded 10 mm, which is just 40 Smith and Wesson wearing a costume.

If you are not going to shoot hot loads, you did not need the 10 mm. 650 street ammo is still $1.50 50 and the platform above it makes fewer compromises. Number eight, the Smith and Wesson 686 Plus 4 in the sevenshot version. And yes, I am ranking it below the six shot. Stay with me. Smith introduced the L-frame 686 in 1980 to sit between the medium K-frame and the big Nframe.

A dedicated magnum that could take a full diet of hot loads without the flame cutting the K-frame model 19 was famous for. The plus variant with the sevenshot cylinder came in the mid 90s and Smith has built it in 357 Magnum 4 in and 6 in on and off ever since. 38 and 357 Magnum, seven shot cylinder, 4 and a/4 in barrel 39 oz. Full lug underlug stainless.

The seventh round is real. The cylinder wall is thinner between chambers, but Smith’s Metallurgy is up to it. Endurance wise, it will shoot as long as the six shot version. Great home defense revolver against the filter. Here is why it lands below the plain 686. The sevenshot cylinder means speed loaders and moon clips are a specialty item, not a standard shelf pulloff.

When the shells went bare in 2020, if you needed a 357 speed loader for a seven shot, you were mail ordering from three vendors nationwide. Logistics matter. One round does not beat a supply chain. That is not opinion. That is just math. 900 bucks street, 750 for a used pre-lock. Pay the premium if you love the platform.

Otherwise, the six shot above it is smarter. Number seven, the Glock 20 full-size 10 mm. The gun that saved Cooper’s cartridge from extinction. Here is the actual 10 mm story, short version. Cooper conceived the cartridge in the late ‘7s. The Bren 10 launched in 1983 and died in bankruptcy. The 1986 Federal Bureau of Investigation Miami shootout.

Two agents killed, five wounded pushed the bureau to adopt 10 millimeter in 1989 in the Smith and Wesson 1076. Recoil ate the bureau alive. By 1990, they downloaded it into 40 Smith and Wesson and the cartridge nearly disappeared. Then in 1991, Glock chambered the G20 and Cooper’s round survived one company at a time. 10 millimeter auto, 15 + one, 4 and a half inch barrel, 30 ounces loaded.

Full house 180 grain out of that longer tube runs 1,300 ft per second and 675 ft-lbs at the muzzle. 15 rounds of that on tap is genuinely impressive numbers. On paper, it beats every service pistol cartridge ever adopted on paper. I want you to hear me on that. Best hunting semi-auto handgun made. I will die on that hill for woods carry, big country hikes, hog hunts. Yes.

Against the filter, most guys cannot shoot it well. Muzzle rise and recoil impulse on a Glock 20 with full power loads is genuinely fatiguing after 40 rounds. So, they train with downloaded stuff. Then in a real moment, the gun kicks harder than they remember and they miss. 650 new, but the revolver at number six matches its energy with one round.

Number six, the Smith and Wesson Model 19 Classic. Bill Jordan’s gun. The Magnum every cop wanted when cops still carried revolvers. Border Patrolman Bill Jordan lobbyed Smith through the 50s to build a K-frame 357 Magnum, a gun a working officer could carry all day. Smith delivered in 1957. The Model 19 became the definitive service revolver for two decades.

Carried by state troopers, sheriffs, and the Federal Bureau of Investigation before the semi-auto wave. Discontinued in 1999, reissued as the classic in 2018 with a modernized barrel design to address the old flame cutting problem the originals were famous for. 38 and 357 Magnum, sixsh shot, 4 and a/4 in, 37 1/2 oz.

125 grain magnum load, 1,450 ft per second, 583t lb. Compare that to the Glock 20 675 with 180 grains. The 357 gives up 90 foot-pounds and gets you a dramatically shorter recoil impulse, faster follow-ups, and a cartridge that has been on shelves for 89 years. Best all-around service revolver ever built. against the filter.

Six rounds is six rounds, and the K-frame is not the ideal home for a steady diet of full house magnum loads. Shoot 38 special and light magnums for practice. Save the hot stuff for carry and the gun lasts three generations. Ignore that rule and you shoot the forcing cone loose in 5,000 rounds. That is the trade.

900 new for the classic, 700 used for a good pre-lock, and the near miss above it costs less. Number five, the Sig P220 and 10 millimeter 5-in hunter. The best shooting 10 millimeter semi-auto on the market. And I mean that. Sig built the P220 in 1975 as their answer to the 1911 and chambered it in 10 millimeter around 2015 under the Elite Hunter branding.

All metal frame, single stack magazine. The classic Sig double-action singleaction hammer setup. Not a race gun, a working gun. And in 10 millimeter, the mass of that metal frame does what polymer does not. It eats the recoil impulse. 10 millimeter auto, 8 + 1, 5 in barrel, 39 oz. Full house, 180 grain at 1,300 ft per second.

Same energy figures as the Glock 20, but the felt recoil is genuinely different. The 10 mm is a shove more than a snap. Compare that to the 357’s fast snap. Same energy, different signatures. For a serious 10 millimeter hunting sidearm, this is the choice. Against the filter, here is the flaw capacity.

Eight rounds in a single stack. Now you have got the recoil of full house 10 mm, the ammo cost of 10 mm, and the round count of a 1911. You are paying premium for premium. If capacity was your reason to pick 10 mm over 357, this gun quietly voids that argument. 1150 MSRP,000 bucks street. Real money. And the revolver at number four costs half and does the same defensive job better.

Number four, the Ruger SP 101 3in 357 Magnum. The little revolver that ran when everything else was out of stock. Ruger introduced the SP 101 in 1989 as a small frame answer to the Smith and Wesson Jframe. Heavier, tougher, and rated for a steady diet of full house magnum loads that the JFrame Magnums genuinely are not.

It has been the working man’s snubby for 35 years. Kentucky Fish and Wildlife issued them. Retired cops carry them. The gun does not quit. 38 and 357 Magnum, five shot cylinder, 3-in barrel, 27 o of stainless. 125 grain magnum out of a 3-in tube gives up velocity. Call it 1,275 ft per second, around 450T-lb, but that is still 9 mm plus P+ territory.

and a gun the size of a paperback. Deep concealment, pocket carry, glove box gun. Against the filter, five rounds and a heavy double-action pull mean you have to actually practice this gun. Most owners do not. They buy it, dryf fire it twice, and stick it in a nightstand. That is not the gun’s fault. That is the owners. 750 new, 550 used.

Best small frame Magnum on the market. But the near miss at number three is the collector tier answer and it costs what a used truck costs. Number three, the Colt Python 4 and a/4 in the 2020 reissue. The revolver everybody’s grandfather wanted. Colt built the original Python from 1955 to 2005.

Hand fitted, polished action, the Cadillac of revolvers. Discontinued for 15 years while used prices went to the moon. Good Originals broke $3,000 by 2018. Colt brought it back in 2020 on a strengthened frame with a redesigned lock work MSRP 1500. The reissue is the same gun the same way only the metallurgy is better. 38 and 357 Magnum six shot 4 and a/4 in full lug barrel 42 oz stainless.

The trigger from the factory is genuinely better than any production Smith double-action I have had on the bench in the last 5 years. That is not me being romantic. That is me with a Lyman gauge. Break is around 3 lb singleaction, 10 lb double. Best shooting factory 357 revolver made today. Against the filter, here’s what cost it. Price and holster availability.

1,500 for the reissue, 3,000 plus for a vintage. That is a lot of money for a gun that does what a $600 Ruger does 90% as well. If you love it, buy it. If you need it, buy the number one gun. 1,500 MSRP 17 street because they are still hard to get. And the runner up at number two is the last 10 mm on this list and it is the one I would actually own.

Number two, the Colt Delta Elite 5in 10mm 1911. The best expression of Cooper’s cartridge in a semi-auto. Full stop. Colt launched the Delta Elite in 1987, three years after Bren 10 collapsed, and it is what kept the 10 millimeter cartridge from dying in the crib. Colt discontinued it in the late ‘9s when the market cooled, then brought it back in 2008 when Cooper’s cartridge revived on the hunting side.

It is a proper 1911 series 80 firing pin block, blued or stainless, wrapped around the hottest common caliber cartridge you can buy over a counter. 10 millimeter auto, 8 + 1, 5 inch barrel, 38 ounces of steel, full house, 180 grain at 1,300 f feet per second. Steel frame eats recoil. Trigger is a proper 1911 trigger. 4 lb crisp.

This is the 10 mm shot the way Cooper meant it to be shot. For a hunting sidearm, a woods gun, a serious auto, for a shooter who trains, this is the gun. Against the filter, here is the flaw, and it is the same flaw as every 10 mm on this list. Ammo $1.50 a round on decent stuff. 250 for Buffalo bore or underwood.

You will not train with this gun the way you should. 1,100 MSRP,000 street and it is still my number two because the number one gun on this list will run on ammo you can find at a truck stop and this one will not. Number one, the Smith and Wesson model 686 4 in sixsh shot 357 Magnum. I already hear it. Six rounds, a wheel gun.

In a world where every channel tells you 15 is the minimum and 18 is normal. That is the rule I told you I was going to break. The rule that says more rounds always wins. Here is why it wins anyway. It shoots the most versatile cartridge ever chambered in a handgun. 38 wad cutter for practice at 20 cents a round, 38 plus P for the recoil shy shooter in your house, and full house 125 grain magnum for defense at 1,450 ft per second and 583 ft-lb.

Same gun, three cartridges, one manual of arms. The L-frame was purpose-built for a full diet of magnum loads. The triple locking cylinder does not shoot loose. It will be running in 2075 the way it runs today. This was never really a contest. I know some of y’all wanted the 10 millimeter to win. I get it. On the muzzle energy chart, the 10 mm looks like the smarter choice.

675 ft-lb beats 583, and the semi-auto holds 15 rounds. Strip the nostalgia and the tribalism off both cartridges, though, and the numbers only point one way. Because ammo you cannot afford to train with is ammo that fails you. And a gun you shoot twice a year is a gun that fails you. That is not opinion. That is just math.

850 Street, 650 used ammo you can find at every gas station, hardware store, and big box store from Knoxville to Gnome. Proven, common, versatile, runs when the shelves are empty. Spec, history, price, it wins all three. Look, training beats gear. The most important tool you own sits between your ears and your trigger finger.

And no cartridge on this list saves a shooter who does not put the reps in. The 10 mm on paper beats the 357 on paper. But paper does not shoot back. If I could only keep three off this whole list, it would be the Smith and Wesson 686 4 in, the Ruger SP 1013 in, and the Colt Delta Elite. and not because they are the flashiest.

The 686 because it does everything. The SP 101 because it goes with me when the 686 will not. The Delta Elite because Cooper was not wrong about the cartridge. He was wrong about who could shoot it. Buy proven, not hyped. Buy the caliber that stays on shelves when things get ugly. And buy the gun you will actually train with, not the one that wins arguments on the internet.

Because the best gun in the world is the one you take out and shoot. All right, your turn. If you could only keep one gun off this list, 357 or 10 mm, which one and why? Drop it in the comments. No judgment, no brand loyalty, no tribalism. Just tell me straight. And yeah, tell me if I got the ranking dead wrong or left something off that belongs here.

Where is the Smith and Wesson 610? Where is the GP 100 match champion? I hear you. I read every single one. The comment scraps are half the fun. Next time we settle the other one, the 44 Magnum versus the 4570 for actual woods carry. That one is going to start even bigger fights and I’ve already got the guns on the bench for it. See you there.

Shoot straight by proven and I will see you
